Application and Kay 16, 1914. Sex-1151280189341.

To all whom it may concern:

' Be it known that I, MARTINcs H. G.On1 n- KERK, a citizen of the United'States, reslding at Lebanon, in the county of Boone and State of Indiana, have invented a new and useful Centrifugal Speedometer for Separators, of which the following is a specification.

My invention relates to centrifugal sgeedometers and has for its particular 0 the indicating of the speed at which shaft ofa cream separator is rotating.

It is an especial object of my invention to provide a speedometer which does not require any spring or other resilient element as one of its members; to (provide a device of improved and simplifie construction operating in a novel manner to indicate the speed at which the center shaft of a cream separator is rotating; and to provide a device that is durable, will-not easily get out of order and which may be manufactured at less expense than speedometers heretofore devised of this class. Iattain these objects by the mechanism illustrated in the accompanying drawin s, in which- Flgure 1 is a ront elevation of my mvention applied to a centrifugal separator; Fig. 2 1s a side elevation of same; Fig. 3 is a cross section on line 33 of Fig. 1.

Similar letters refer to similar parts throughout the several views.

Referring to the accompanying drawings, A indicates a dial late having appropriate graduations to in icate spec of rotation of the center shaft J of the se arator.

B indicates a finger by WhlCh the speed ject the is indicated. Finger B is mounted on pivotv C, and connected by connecting member L to a. vertically slidable connecting rod D, mounted in sleeve E. Connecting rod D has its lower end supported by a vertically movable disk member F, which in turn is mount-' mounted and adapted to be adjusted, and a suitable clamping nut C on the pivot adapted to secure finger B in any desired adjusted position from time to tlme as may be necessary. As indicated'b the drawings, this device is built in and directly connected with the center shaft of'centrifugal separaters. f I

In the operation of this speedometer, it will be observed that springs have been eliminated, and that in its operation the centrifugal movement of the elements indicated by H and G, which are pivotally connected with the center shaft, ralse disk member F,

as the speed is increased, which in turn raises connecting rod D and connecting member L and gives a rotary movement to finger B, the return of the various members vto their ori 'nal osition when speed slackens being efli cted by avity.

he accompanying drawings are illustra tive of my invention, but minor changes in details of construction and arrangement of arts not constituting an essential departure mm the disclosure are within the contemplation of my invention.

What I'claim is: I r

1. A centrifugal speedometer comprising opposite centrifugal elements each having a weighted portionancl an arm with an arcuate edge portion, a disk member supported by the centrifugal elements, a separator center shaft to which the centrifugal elements are pivoted and on which the disk member is mounted, a connecting rod having its bottom endsupported and actuated by the disk member, a. sleeve in which the aforesaid connecting rod is vertically mov able, a graduated plate member, a speed-indicating finger pivotally mounted thereon, and means connecting the aforesaid finger with the above-mentioned connecting rod, substantially as set forth.

2. The combination with a center shaft of a dial plate, a speed indicating finger pivotally mounted on the dial plate, a disk member mounted on the center shaft and free to move vertically thereon, substantially vertically-disposed gravity-controlled members operatively connecting the disk member and the speed-indicatlng finger, and centrifugallycontrolled means pivoted to the center shaft and actuating the disk member.

3. A centrifugal speedometer comprising 10 members.

in combination with a center shaft a dial plate, a pivotally-mounted speed indicating finger on the dial plate, means to secure said finger in adjusted position, gravity- 5 controlled members operatively connected with and disposed parallel to the center shaft and centrifugally actuated members pivoted to the center shaft operatively connected with the aforesaid gravity-controlled 4. A centrifugal speedometer'comprising centrifugal elements, a disk member supported by the centrifugal elements, a separator center shaft to which the centrifugal 16 elements are pivoted and on which the disk member is mounted, a connecting rod having its bottom end supported and actuated by the disk member, a graduated plate member, an adjustable speed-indicating finger pivotally mounted thereon, and means con-' necting the aforesaid finger with the abovementioned connecting-rod, substantially as MARTINUS H. G. OEDEKERK.
